What happened to the lightning strike in Yunnan? How to avoid rain in rainy days? The reporter learned from the Propaganda Department of Qiubei County Party committee that on the afternoon of August 1, a lightning strike occurred in the Xiaopo village group of the village committee of twist village, Tianxing Township, Qiubei County, Yunnan Province, killing 4 children and injuring 3 children.
The reporter learned that on August 1, 7 children went to the back mountain of the torsional breeding farm to collect fungus. When the thunderstorm came, 7 children went to the tree to shelter from the rain. Four children died and three children were injured due to the lightning strike.
After receiving the report at 16:10, Qiubei County Party committee and County People's government immediately organized a working group to go to the scene to carry out the work of medical treatment, civil affairs assistance and family appeasement.
At present, three injured children are being treated in the county hospital, with no life-threatening. The local government and civil affairs department are carrying out the rehabilitation work for the families of four dead children.
Why can't we shelter under the trees in rainy days?
There are three forms of lightning damage to people staying under trees:
When the human body contacts with the tree, the strong lightning current flows through the tree trunk and produces a high voltage to knock people down. This is because the human body is in direct contact with this high voltage, usually referred to as contact voltage injury.
Secondly, although people are not in contact with trees, when lightning current flows through trees, it will generate a high voltage enough to discharge through air and cause injury, which is usually called counterattack injury.
Another is that although people are not in direct contact with the tree, they are also a certain distance away from the tree, but because standing under the tree, when a strong lightning current flows into the ground through the tree and spreads around, it will generate different voltages in different places, and there is a potential difference between the two feet of the human body standing, so there is a current flowing through the human body to cause injury. It is usually called step voltage damage. The discharge object of thunderstorm is selective. The lightning current always chooses the nearest and most conductive path to discharge to the earth. That is, it is easy to discharge the highest object in the occurrence area.
In an open place, trees and people are always the highest, so they are often hit by lightning. Therefore, open fields, beaches, sea and even football fields and golf courses are very dangerous places in thunderstorm weather.
Scientific self-protection:
In Thunderstorm prone days, first of all, try to avoid these open places. When you see lightning in the countryside, you hear thunder immediately, which indicates that you are in the near thunderstorm environment. You should stop walking immediately and squat down immediately with your feet together. This can lower the effective height of the human body.
If time permits, the biggest possibility is to squat in a nearby low-lying place or cave. At this time, remember that low houses and trees are not safe places.
